- Abstract
Objective: In this study, it is aimed to create a brain atlas by parcellating the threedimensional images of the structures in the brain in magnetic resonance (MR) images. It is aimed that the anatomy atlas created for this purpose will contribute to both anatomy education and clinical studies. Materials and Methods: In our study, MriStudio, a fully automatic parcellation software, was used on brain MR images. MriStudio consists of three software programs: DTIStudio, DiffeoMap and ROIEditor. Using MriStudio software, the desired brain structure is saved as MASK (separating the image from the background and assigning labels). ROI atlas was applied to obtain ROIs for 189 brain regions. Each brain region image was registered at each slice level and in three dimensions with MricroGL software. Results: The volume values of three methods (manual, MriStudio and Ibaspm) were obtained on brain magnetic resonance images. By accepting manual measurements as the gold standard, it was observed that the values obtained with MriStudio were closer to manual measurements. The volume and cross-sectional image of 189 regions of the brain were obtained. Conclusion: It is possible to obtain atlases of anatomically normal individuals using magnetic resonance images. Obtaining the volume values of brain structures with such individual atlases will be a second advantage. In addition, we believe that it will be useful in understanding the brain anatomy and contributing to the diagnosis of clinical problems by showing the structures in the brain cross-sectionally and in 3D.
